For those servers which are experiencing bugs including but not limited to:
- Players glitch through the aircraft's floor when the aircraft takes off.
- Level fails before the aircraft takes off.
MAKE SURE your server isn't running the plugins that produce massive amount of entity traffics. Since my map has already pushed the entity limit to a risky level, if server plugins keep spawning more entities, there is no guarantee what bugs will be encounter.

This is just an ALPHA version. A lot of things in this map need to be improved, so do not expect too much from it.
Any glitch report, difficulty suggestion,complaint about item price being too high/low, military language suggestion, optimization suggestion and so on will be welcomed. Let me know your thinking about this map. I will put the suggestions on my list and do my best to enhance the map accordingly.
Hope you enjoy what this map has so far.
Important notes:
- Do not change the gravity setting (default value: 800)
- Enable color correction setting
- Run this map in vanilla settings, avoid gun menu script that gives player thermal weapon (Flare gun, molotov)
**Item wiki:**
You will be given a weapon case when you buy a player-controlled turret. You can put the case everywhere you want. To deploy the weapon, simply crouch and press E to the handle of the case(dont jump onto it to do that if you don't want to get stuck) then a gun turret will come out. To use the gun, press E to the gun handle.
When you get an auto turret, drop it where you want to deploy it. After 3 seconds it will be automatically deployed (glowing green). To suspend its function, press E to it and you will see it glowing blue. To pick up again, press E while it's in suspension state (so if it's deployed, press E twice).

**Misc**
Collect crystals and bring to the tower to gain crystals. To buy a weapon, walks to the tower and you will see an item name appearing on your screen. To switch to the next/previous item name, turn your face a little to the left/right and press the "next"/"previous". To buy, click the item name by pressing E.
To load ammo for turret, grab specified ammo type and push it to the turret. The indicator light on the turret roughly shows how much ammunition is stored. Red light means low ammo, yellow means sufficient ammo, green means no need to refill with more.
You cant mine crystals in first two objectives

Batteries are used to power the floor lamps located near the tower
Tower has to be alive throughout the game, as well as players. When it glows red, that means it's dying.
